Automatic Basket Strainer is large bottom chamber where theline velocity gets reduced. Flow Continues upward passing in a radial manner through the sealed screen element.Unwanted materials are trapped on the inside of the filter element screen.The fluid keeps getting filtered and comes out clean through the outlet nozzle. As the filter screen gets loaded with dirt, the differential pressure keep raising.There is hollow full flow backwash arm extending the full length of the filter element. This can rotate and is piped to atmosphere through a backwash valve.When the differential pressure crosses the pre-set limits. The backwash valve opens the system to atmosphere causing a high velocity reverse flow across the isolated section of screen. Dirt and debris are flushed out from this segment of the screen into the backwash arm and out of the strainer via the backwash piping.During the backwashing cycle the main flow is uninterrupted and continues to be strained in the normal manner. The control system would automatically close the backwash valve after the screen is cleaned.
